For 1080p video at 30 frames per second, the bitrate range is 3,000 to 6,000 kbps.
For full HD videos that have a standard frame rate (1080p, 30fps) – Ideal bitrate 3,500 to 5,000 kbps.
The best frame rate for live streaming should be at least 30fps for live video. While FPS is one of the most important technical aspects of online streaming, it is not as important as video quality.
For most viewers, a bitrate for 6000kbps will be too high. Unless you are guaranteed to get quality options on your stream, you should opt for lower settings instead. A good starting point would be to stream at 720P at 60FPS.
Anything between 24 to 30FPS should do just fine, given a decent amount of animation for explanation can also be accommodated in the given frames.
For gaming, 60fps way more smoother than 30fps to a human eye. Going upto 144fps, you see a noticeable difference. Between 144fps & 240fps, you dash say that the difference isn't that big. For gamers, 1440p 144Hz is the sweet spot right now, you get higher resolution than 1080p with high refresh rate.
Some experts will tell you that the human eye can see between 30 and 60 frames per second. Some maintain that it's not really possible for the human eye to perceive more than 60 frames per second.
For streams with 720p resolution and 30fps, you can use a bitrate as low as 2,500 kbps if your internet is particularly weak. But you'll likely want to up that bitrate to 3,000 to 4,000 kbps. No matter what resolution and fps you stream with, your optimal bitrate will depend on the power of your internet.
Best live streaming settings for Twitch
Twitch recommends different bitrate settings based on your chosen resolution and framerate (frames per second, or fps). The most common resolution options on Twitch are 1080p and 720p, at 60 fps or 30 fps. Bitrate requirements on Twitch: 1080p @ 60 fps: 6000 kbps.
Why is this important to know? Well, your framerate will work in tandem with your bitrate — and you may have to sacrifice resolution for a larger framerate. If you do have to choose between framerate and resolution, go with whatever you think is more important, but here are a few simple examples to help you out.
A good rule of thumb is for the bitrate of your stream to use no more than 50% of your available upload bandwidth capacity on a dedicated line. For example, if the result you get from a speed test shows that you have 2Mbps of upload speed available, your combined audio and video bitrate should not exceed 1Mbps.
As a rule of thumb streaming full HD video, depending on the framerate, lands between 3500 and 6000 kbps. 720p HD is more forgiving to an entry-level streaming setup, starting at about a 2500 kbps bitrate and capping at 4000.
If you're shooting solely for streaming, you should go with 30 fps. 30 fps — Used for non-broadcast video in the U.S. and elsewhere. 50 fps — High frame rate video in Europe for broadcast or streaming. 59.94 — High frame rate video for U.S. broadcast.
Video bitrate is directly correlated to video quality. Higher the bitrate, higher the video quality. But bitrate is not the only parameter affecting visual quality, pixel also plays a role in video quality. Bitrate is generally represented by kbps which essentially means kb (kilobit) of data per second.
Digital audio is digital information. That information can be dense or sparse, high-quality or low. Bitrate is the term used to describe the amount of data being transferred into audio. A higher bitrate generally means better audio quality.
OBS Output Settings
Of course, you can select a higher video quality if you choose. If you are only streaming audio, you can get away with bitrate settings as low as 64 kbps. However, for better quality, you should up your audio bitrate settings to 192-320 kbps.
Twitch specifies a maximum bitrate (bits transferred per second of video) of 6000 kbps, but many Twitch streams use less. While a higher bitrate can result in higher quality video, it may reduce the number of potential viewers as some computers or Internet connections cannot handle higher bitrate video.
The best bitrate for 1080p 60fps on Twitch is 6,000 kbps provided if you have a strong internet connection. However, you can opt for 1080p 30fps that requires at least 4,500kbps if you have a slower connection.
There is no higher bitrate limit for Partners. I am one. 8000kbps is simply a word-of-mouth, entirely unofficial "known good" value that mostly works. There is no technologically-enforced upper limit to how much bitrate you can use.
Network congestion is the main culprit. Having a static bitrate can cause frames to drop because your connection is unable to keep up and will drop frames to improve the stability of your stream and minimize latency.
BUT, a dog's flicker fusion rate is higher, usually around 70-80 frames per second. So, TV looks choppy to a dog, as he can see the breaks between each frame.
A team of researchers at INRS have smashed the ten trillion fps barrier with their T-CUP ultra-fast camera. A research team at the INRS Universite De Recherche has recently built the world's fastest ever camera called T-CUP. It is so quick it is able to capture 10 trillion frames per second (fps)!
The term 8K doesn't really apply to how eyes work, but if we reduce the complex nature of sight down to this marketing buzzword then yes, the human eye can see in 8K and beyond. The reason for this hesitation is that eyes don't see in pixels, or use resolutions - no optician has ever said you can only see in 720p.
